CLAMP FOR WELDING TIRES.

SPECIFICATION forming part of Letters Patent No. 769,530, datedSeptember 6, 1904.

Application filed May 14, 1904-.-

Tr) 10/] 11410711 it 71mg concern.-

.Be it known that I, OHARLEs S. BLAKER, a citizen of the United States,and a resident of \Vorth, in the county of Vorth and State of Missouri.have invented a new and Improved Clamp for \Velding Tires, of which thefollowing is a full, clear, and exact description.

My invention relates to clamps for use in heating and objects are toprovide such a device for holding the ends of tires in their properrelation for making a lap-weld, enabling the smith to dispense with theservices of a helper.

It consists in the various features hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a. perspective view of one embodiment of my invention,showing a tire held by it in position for welding. Fig. 2 is an endelevation thereof, and Fig. 3 is a side elevation looking from the leftin Fig. 2.

Y designates a yoke which, as here illustrated, consists of a bar 10 ofsuitable metal, preferably of flattened form and having at each end anarm 11, extending substantially at right angles from it. Each arm isinclined from the general plane of the bar at 12, so that the outer endwill lie in a planeapproxifnately parallel to that of the bar. At the.)uter extremity of each arm is a clamp, here shown as integral with theyoke and formed )y bending the arm back at 13. Through '.he clampmembers 13 operate set-screws H, ierving to force the work against theopposite aide. The faces of the clamp members oppowelding tires; and itsprincipal Serial No. 207,951. No model.)

' that of the are upon which it is desired the l l l l clamp membersshall lie. The parts are so proportioned that the lower side of thecurved bar approaches the general plane of the clamps, as isparticularly shown in Fig. 2 of the drawings. This brings the deviceinto contact with the surface upon which it may rest at separatedpoints, furnishing a stable support, which facilitates the introductionof the tire and the operation upon it.

In use the tire is bent and its ends introduced into the clamps with thelapped por tion lying between them and there secured by turning down thescrews, the introduction being aided by the inclined portions of thearms at 12, which guide the tire into place. It is now ready for weldingor any operation which it may be desired to perform upon it.

Having thus described my invention. 1 claim as new and desire to secureby Letters Patent 1. A clamp for welding tires comprising a yoke, theopposite arms of which extend back upon themselves to furnish a clamp,and a setscrew extending through each clamp.

2. A clamp for welding tires comprising a bar having arms inclined fromthe general plane thereof, then extending outwardlv and finally backupon themselves, and screws threaded through the last-named portions.

3. A clamp for welding tires comprising a bar having the form of an arcof a circle and being provided with arms inclined from the general planeof said bar to an amount ap- :ite these screws preferably lie insubstanf ially the arc of a circle, this lending itself to he easyintroduction of the bent tire T and maintaining the same in practicallyits true urvature. The proper positioning of these lamps may be effectedby bending the bar 0 as is here illustrated, the curvature beingproximating its curvature, then extending outwardly and finally backupon themselves, and screws threaded through the last-named portions.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
